/* NOTE: There are 2 ways to achieve the above goal.
* 1) Get all items that have the correct itemId, loop through them until the lowest enchantment
* level is found. Repeat all this for the next item until proper count of items is reached.
* 2) Get all items that have the correct itemId, sort them once based on enchantment level,
* and get the range of items that is necessary.
* Method 1 is faster for a small number of items to be exchanged.
* Method 2 is faster for large amounts.
*
* EXPLANATION:
* Worst case scenario for algorithm 1 will make it run in a number of cycles given by:
* m*(2n-m+1)/2 where m is the number of items to be exchanged and n is the total
* number of inventory items that have a matching id.
* With algorithm 2 (sort), sorting takes n*log(n) time and the choice is done in a single cycle
* for case b (just grab the m first items) or in linear time for case a (find the beginning of items
* with correct enchantment, index x, and take all items from x to x+m).
* Basically, whenever m > log(n) we have: m*(2n-m+1)/2 = (2nm-m*m+m)/2 >
* (2nlogn-logn*logn+logn)/2 = nlog(n) - log(n*n) + log(n) = nlog(n) + log(n/n*n) =
* nlog(n) + log(1/n) = nlog(n) - log(n) = (n-1)log(n)
* So for m < log(n) then m*(2n-m+1)/2 > (n-1)log(n) and m*(2n-m+1)/2 > nlog(n)
*
* IDEALLY:
* In order to best optimize the performance, choose which algorithm to run, based on whether 2^m > n
* if ( (2<<(e.getItemCount() * _amount)) < inventoryContents.length )
* // do Algorithm 1, no sorting
* else
* // do Algorithm 2, sorting
*
* CURRENT IMPLEMENTATION:
* In general, it is going to be very rare for a person to do a massive exchange of non-stackable items
* For this reason, we assume that algorithm 1 will always suffice and we keep things simple.
* If, in the future, it becomes necessary that we optimize, the above discussion should make it clear
* what optimization exactly is necessary (based on the comments under "IDEALLY").
